UPHOLSTERING-MACHINE.

Specification of Letters Patent.

Patented Nov. 3, 1908.

Application filed October 25, 1907. Serial No. 399,188.

To all whom it may concern:

Be it known that I, ISAAC KARPEN, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented a new and useful Improvement in Upholstering-Machines, of whichthe following is a specification.

My invention constitutes an improvement on the upholstering machine'described and claimed in my application No. 390,024, filed August 24,1907.

My primary object is to provide improved fastener-holding means for usein connection with a machine of the character indicated.

The invention is illustrated in the accompanying drawing, in which-Figurc l represents a broken sectional view of a mold for atufting-machine having its presser-board, or follower, equipped with myimproved fastener-holding means, and showing a mattress, or pad, inprocess of formation; Fig. 2, a similar view showing the edge-rail ofthe mold removed and the covering of the mattress, or pad, turned up forconnection with the fasteners; Fig. 3, a perspective view of my improvedfastenerclip with an individual fastener-retainer; Fig. l, a broken edgeelevational view of the saunel Fig. 5, a broken perspective view of afollower-board equipped with my improved individual fastener-clips,illustrating how the same may be applied to an irregularly-shaped edge;Fig. (3, a broken sectional view showing a modification of thefastenerclip; and Fig. 7, a broken perspective view showing a stillfurther modification.

In the drawing, A represents a mold for a tufting-machine having abottom A1 and a removable edge-rail A2; B, the follower, orpresser-board, of the nold; and C, individual fastener-clips applied tothe edge of the follower.

Each clip C comprises a vertically-disposed fastener-guide c equipped atits upper and lower ends with rearwardly-turned attaching-flanges c; anda spring-retainer c2 connected with the lower flange. The fastener-guidec is provided with a T-slot c open at its upper and lower ends and openat the front of the guide to receive the shank of the fastener, asindicated at ct. The spring-retainer c2 is attached at its rear end tothe rear portieri of the lower flange c1 and its front end projectsacross the lower end of the T-slot, as will be clearly understood fromFigs. 3 and 4. The flanges c1 are adapted to embrace the upper and lowersurfaces of the follower-board, as illustrated in Fig. 5, and aresecured to the followerboard, as by screws c5. The head of the fasteneris received in the T-slot, the shank of the fastener projecting throughthe open channel c4, as clearly illustrated in Fig. 1, the head of thefastener resting upon the retainer G2.

D represents a mattress, or pad (inverted during tufting), having aninner fabric (usually canvas) d, an outer covering (usually leather orimitation leather) (Z1, and a fringe or flap d2, As is known, themargins of these fabrics are preparatorily perforated to receive thefasteners. After the fasteners are entered and clenched, thefollower-board may be lifted from the pad, the retainers c2 yielding` topermit the heads of the fasteners to pass.

In the construction illustrated in Fig. 6, C1 represents a modified formof my improved fastener-clip, the construction being very similar to theconstruction already described. In this construction, however, theretainer spring c is dispensed with, and a shoulder c? is formed at thebase of the guide c for the fastener-head to rest upon, the walls of theguide being sufficiently yielding to permit the fastener-head to passsaid shoulder when the follower-board is lifted from the pad.

Fig. 7 shows a still further modification, in which C2 represents afastener of the same general construction as those already described. Inthis construction, the retainer springc2 is dispensed with, and thefront wall of the fastener-guide c is equipped at its base with arearwardly or inwardly turned lip cg upon which the fastener-head mayrest.l In this construction, the lip and wall of the guide to which itis attached will yield sufliciently to permit the head of the fastenerto pass when the follower is lifted from the pad.

The invention is applicable to the follower of any pad-forming machine,regardless of whether or not the tufting operation is performed in thesame machine.

It is to be observed that by omitting the fastener-retainer rods which Ihave heretofore employed and providing individual retainers for thefastenenguides, I not only render it possible to apply my invention to afollowerboard having an irregularly shaped. edge, but l also render itpossible to apply the fasteners eloser to the body of the pad, ormattress, than has heretofore been possible.

What l regard as new and desire to secure by Letters Patent is:m

l. The combination with a follower of a pad-formingl machine, offastener-guides applied to and crossing an edge thereof and eonsirueledwith individual fastener-retaining means.

Q. The combination with the follower of a {md-forming machine, ofindividual fastenerguides applied to an edge thereof and eX- tendingperpendicular thereto and equipped with individual fastener retainers,for the purpose set forth.

Si. The combination with the follower of a pad-forming machine, offastener-guides applied to an edge thereof and extending substantiallyperpendicular thereto, and indig vidual fasteneiretainers at the lowerportions of said fastener-guides.

4'. The combination with the follower of a pad-forn'ling machine, offastener-guides at an edge thereof extending perpendicular to thefollower, and spring-retainers projecting into the path of the heads ofthe fasteners at the lower end-portions of the fastenerguides.

5. A fastener-clip for the purpose set forth comprising a fastener-guideequipped with attaching means, and a fastener-retainer extending ,intothe path of the head of the fastener, for the purpose set forth.

G. A fastener-clip for the purpose set forth comprising a fastener-guidewith a T-shape slot, attaching flanges projecting rear *ardly from saidguide, and a retainer'- spring carried by the lower flange, for thepurpose set forth.
